The first step is to get a real default route in your routing table.  Usually 
you'll see a default to null0 when summarization is configured.  I'd make sure 
there is no summary-address configured, which there probably isn't.  

I might try to remove eigrp on the ASA.  Verify the OSPF route is in the table, 
then add the redistribution back in.  Without trying it I'd say based on the 
outputs below that the ASA thinks its doing a summarization for eigrp be it on 
the interface or something.
